The problem for most buyers with a new seller is simple BTC has no chargeback option. If someone sends you 1 btc and you take off oh well.
Thus escrow services someone like me offers escrow why me I have been around for 2 plus years done thousands in business on the forum. I have been on ebay for 10-11 years and have a perfect record.
The buyer send me the coin I store it you send him the gear he says it is good I send you the coin. For 1 btc I would charge .005 btc to do the deal. which is 1/2 of 1 percent. There are others that offer escrow they have fees of 1 to 2 %.
Both buyer and seller can look me up.
